Umehluko phakathi kwemaski ye-FFP2 nemaski yokuhlinzwa|KENJOY

Uyini umehluko phakathi kwe-aI-FFP2 imaskikanye nemaski okuhlinzwa?Yiziphi izici phakathi kwalokhu kokubili?Okuqukethwe okulandelayo kungakunikeza ukuqonda okungcono komehluko phakathi kwamaski amabili.Ngethemba ukuthi izoba usizo kuwena ngemva kokuyifunda.

Izinzuzo kanye nebubi bokuzivikela

Amamaski e-FFP2 angavimbela kangcono izinhlayiya eziyingozi, kodwa abantu abaningi bayaqhubeka nokukhetha imaski yokuhlinzwa.Isici semaski yokuhlinzwa yezokwelapha ukuthi ivikela abanye ekuphefumuleni komuntu oyifakile, kodwa imaski ye-FFP2 ivikela ogqokile kanye nabanye kuzo zombili izinkomba.

Ingabe ukuhlinzwa kwezokwelapha kwanele?

Njengoba amagciwane eqhubeka nokudala umonakalo emoyeni, imaski yokuhlinza isasebenza, futhi ukugqoka noma iyiphi imaski kungcono kunokungayigqoki nhlobo.Kodwa-ke, ngezikhathi zamagciwane athathelwanayo, sidinga imaski ye-FFP2 ngoba imaski yokuhlinzwa yezokwelapha ayisanele ukubhekana negciwane elisabalalayo, elisakazeka emoyeni ngokushesha kunanoma yiliphi igciwane elaziwayo.

Imaski ekhethwayo ye-FFP2 esikhaleni

Abakhiqizi be-FFP2 bancoma ukuthi bahlale besebenzisa imaski ye-FFP2 ezindaweni ezivalekile.Ngaphezu kwalokho, lapho abantu befuna ukuhlangana nabantu abasengozini, kufanele futhi bakhethe imaski ye-FFP2.

Yize lo mkhuba usushintshile, bayanda abantu abagqoka imaski ye-FFP2 ezindaweni zomphakathi, kodwa abanye abantu bayaqhubeka nokukhetha imaski yokuhlinzwa.Ochwepheshe bathi ngakolunye uhlangothi, inkinga yentengo, kanti esinye isizathu ukunethezeka.Uma igqokwe kahle, ingabangela ukungakhululeki ezindlebeni isikhathi eside futhi ishiye namamaki ebusweni.

Imaski yokuhlinzwa yezokwelapha

Umehluko phakathi kwemaski yokuhlinzwa yezokwelapha kanye nemaski ye-ffp2 ukuthi izinga lokuvikela lemaski yokuhlinzwa liphansi ngebanga elilodwa, futhi imaskhi yokuhlinzwa yezokwelapha ihlangabezana nezidingo zobuchwepheshe zemaski yokuhlinzwa yezokwelapha.Ngaphansi kwesimo sokugeleza komoya (30 ±2) L/min, ukusebenza kahle kokuhlunga kobubanzi obumaphakathi be-aerodynamic (0.24 ±0.06) μ m i-aerosol ye-sodium chloride ayikho ngaphansi kuka-30%.Ukusebenza kahle kokuhlunga kwamagciwane ngaphansi kwezimo ezithile, ukusebenza kahle kokuhlunga kwe-aerosol ye-Staphylococcus aureus enobubanzi bezinhlayiyana ezimaphakathi (3 ±0.3) μ m abukho ngaphansi kuka-95%.Ngaphansi kwesimo sokusebenza kahle kokuhlunga kanye nezinga lokugeleza, ukumelana nokuphefumula akudluli i-49Pa futhi ukumelana nokuphelelwa yisikhathi akudluli i-29.4Pa.

Amamaski okuhlinzwa aboniswa ezinkomba zobuchwepheshe, ikakhulukazi ukuthi umthelela wesithiyo wezinhlayiya ezingenawo amafutha ezingama-micron eziyi-0.3 ezidingwa imaski yokuhlinzwa yezokwelapha zingaphezu kwama-30%, imaski yokuvikela yezokwelapha efana nemaski e-ffp2 ingama-95%, kanti umgoqo wamagciwane wama-microns ama-2. ububanzi budinga ukuba bukhulu kuno-95%, okungukuthi, izinga le-BFE95, elingaphansi kancane kumamaski we-ffp2, kodwa hhayi kubi kakhulu.

Umphumela wokuvikela ungcono kakhulu uma ugqokwe ngokunembile

Abakhiqizi be-FFp2 bagcizelele ukubaluleka kokugqokwa okunembile.Uma kukhona igebe phakathi kwekhala nezihlathi, noma uma ugqoka imaski efanayo izinsuku ezimbalwa zilandelana, imaski iyize, ngisho noma ugqoke i-FFP2.Omaski be-FFP2 abavikeli uma bengavalwanga kahle ebusweni, ngaphandle kwalokho igciwane lisengakwazi ukungena noma liphume, yingakho abantu bengenwa igciwane yize begqoke imaski.

Lona umehluko phakathi komamaski be-FFP2 namamaski okuhlinzwa.Uma ufuna ukwazi okwengeziwe ngamamaski e-ffp2, sicela ukhululeke ukusithinta.
